.wmn RING ROLLING MACHINE Application filed April 6,1931. jSerial no. 527,915.

This invention relates to new and useful improvements in a wire ringrolling machine. It is customary to manufacture lamp shades with wire rings of various diameters BI and gauges. It is an object of this invention to produce a machine which is capable of winding various gauges of wires to various diameter sizes so that thereafterthe wound wire may be out to form rings. It is another object of this invention to produce a wire rolling machine which is characterized by a frame supporting a plurality of rotative wire winding drums at a convenient height from the floor for the comfort of the operator, and a plurality of arms pivotally mounted on said frame and supporting other sizes of Winding drums, and means for holding the arms inythe pivoted position to the front of the first mentioned drums so as to beat the convenient height specified. I I

Furthermore, as another object, this invention proposes that all of the various wire winding drums previously mentioned, be removable, and provision of means he made to detachably hold them in place.

Another one of the objects of this invention is the arrangement of squared spindle portions on the wire winding drums for accommodating a crank for manual turning.

Another object of this invention is the provision of a chart with the machine to guide the operator in the manufacture of the wire material.

Another one of the objects ofthis invention is'the provision of a top winding drumcapable of normally maintaining the rear position and to be movable to the front so as to be at the convenient height previously mentioned, and a bottom winding drum nor mally depending downwards and movable to the front and upwards to the convenient height.

r Furthermore. as another object, it is proposed to provide means to hold the lower arms in place and means to release the lower arms when the drum which is set behind on the main frame is to be used.

Furthermore, this invention-has for an coils of different sizes and thus save time and" other object the provision of a wire rolling I machine which is of simple, durable con: st-ruction, dependable in use, efiicient in operation, and which can be manufactured and sold at a reasonable cost. For further comprehension of the invention, and of the objects and advantages there:

'of, reference will behadto'the. following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings,-f0rming a material part of this disclosure I Fig. 1 is a front elevational view of a machine constructed according to this invention.

Fig. 11 is a chart for use in conjunction with the machine to save time.

The wire rolling machine comprises a frame 10 which is of substantially U-shaped form and is mounted upon a'stand 11. The U-shaped member has a pair of vertical arms indicated by reference numerals 12.

A plurality of wire winding drums 15 and 16 are rotatively mounted in the arms 12 at a convenient height from the floor so that the operator may work in comfort. Each of these drums are rotatively mounted in apertures 56 formed in the right arm 12 while in the left arm 12 they engage in-slots 57 so H that only one of the ends may be removed to ends and removable from the support 12 at their other ends merely for the purpose of coils wound upon them. When one of the ends of the drums is lifted, only half the weight of the drum need be contended with since the other half of the weight may be supported. Trunnions 18 project from 'the ends of the drums 15 and 16 and it is by these trunnions that the drums are supported in the arms 12.

On each of the arms 12 there is mounted an upper arm 28 which is .pivotally supported at 29. The arms 28 are of substantially L form with the short ends 30 extended inwards. A'peg 31 is mounted in each of the arms 12 and forms a stop for the arms 28 so as to limit backward motion to the position shown in full lines in Fig. 2. A wire winding drum 32-is provided with a spindle .33 which extends into a slot 28 formed in the end of the left arm 28. Right arm 28 has merely an aperture 28 through whichthe spindle passes. Catch 34 is mounted upon the left arms 28 and serves to clamp the spindle 33 in place. The catch 34 comprises a member pivotally mounted at its outer end as indicated by reference numeral 35 and capable of encircling around a portion of the spindle 33. A spring lock 20 is mounted upon the plate 34 engageable within anaperture formed with the arm 28 so as to keep the member 34 in its latched position.

A pair of lower arms 36 are pivotally mounted at 37 upon the lower portions of the arms 12 and are also of substantially L shape but have their smaller ends outside. A wire-winding drum 38 has a spindle 39 engaged in slots formed in the ends of the arms 36. A catch 19 is mounted on each of the arms 36 and serves to normally hold the spindle in place; The inner ends of the arms 36 are formed with a grooved portion 40 and holes capable of being engaged by a stem 35 of a catch 20 mounted in the arms 12.

The catch 20 is clearly shown in detail in Fig. 8 wherein a casing 21 is illustrated threadedly engaged into the arm 12 or other element supporting the catch and has an'interior hollow 22. A spring 23 is disposed in this hollow and acts between a flange 24 onan extendible stem 25 and afront plate 26. 'The stem 25 is provided with ahead 27. for manual moving.

In F ig. 11 a table has been illustrated as a time saver in the use of the Various drums. Qn the chart some of the sizes of the rings are indicated by alphabet while others are shown by numerals, the idea is that the drums 15, 16 and 32 are quite heavy and are mount-' ed "upon the machine so as not to be removable and are therefore indicated by numerals. The three drums 38, 58 and 39 are much lighter in weight and may be substituted onefor the other upon the machine as is desired according to the sizes of rings to be manufactured, and to distinguish these drums from the ones which cannot be removed they are marked with letters. This rrangement helps the operator to quickly locate the drums and the sections which he wishes to use thereof without undue compli- If all of the drums were marked with numbers or if all were marked with letters, the quantity of the same types of symbols involved would cause more confusion than the arrangement proposed. In addition, the chart directs the gauge wire to be used to obtain a desired size of ring. For example, when a number 10 wire is used and it is required to make a spring having a 7 outside diameter, thesection marked numeral 18 should be used.

The operation of the device may be understood by assuming the apparatus in the condition shown in Fig. 2. In this condition the lower winding drum 38 is in the act of being moved to its front position. This front position is indicated by the dot and dash lines 53. The dot and dash lines 54 indicate the front position of the drum 32. In the front position of the drum 32, the arms 28 rest against the spindles 18 so as to maintain the position. The front position of the drum 38 is maintained by the catches 20 which are located in both the arms 12 and act against the grooves 40 in the arms 36. A wire may be inserted in the aperture 15' of any of the drum sections and revolution of the drum by means of the crank 55 causes the production of a coil of wire 46. The coil of wire 46 may be engaged upon a jig 44 having a cut-out 45. Cutting of the coil along theline 47 will produce rings of wires.

When it becomes necessary to wind a coil of a certain diameter, the chart may be consulted for ascertaining which of the sections of the drums should be used. In examining Fig. 1 it will be noticed that each of the sections is provided with a different indicating numeral.

It is intended that normally the drum 32 be to the rear and the drums 38 depend downwards. Then eitherdrum 15 or 16 may be used. In use, a crank 55 is placed on the squared end of the spindle which supports either of the drums and the drum may be turned. The crank is removable so that one crank is sufficient for the machine in that it may be engaged on any of the spindles.
